Product details
Overview
MSP430FR5967IRGZR from Texas Instruments is a 16-bit ultra-low-power FRAM microcontroller in a 48-pin VQFN package, featuring 32KB nonvolatile FRAM, 1KB RAM, 12-bit ADC with 16 external channels, RTC with calendar/alarm, and dual eUSCI modules supporting UART, SPI, and I²C. It operates from 1.8 V to 3.6 V and targets battery-powered sensor nodes and data loggers.
For engineers reviewing the MSP430FR5967IRGZR datasheet, MSP430FR5967IRGZR pinout, MSP430FR5967IRGZR application, or MSP430FR5967IRGZR equivalent, key selection criteria include FRAM endurance (10¹⁵ writes), LPM3.5 current (0.25 µA typical), RTC calendar support, capacitive touch I/O capability, and UART/I²C bootloader compatibility.
Technical Context
The MSP430FR5967IRGZR implements the CPUXV2 16-bit RISC core with 16 registers and integrates a 32-bit hardware multiplier, three-channel DMA, and a 16-bit CRC module. Its clock system includes factory-trimmed DCO (up to 16 MHz), LFXT (32 kHz crystal), and HFXT (high-frequency crystal) oscillators - all explicitly supported per device comparison table.
It features two independent eUSCI modules: eUSCI_A0/A1 for UART (with auto-baud detection), IrDA, and SPI; eUSCI_B0 for I²C (multi-address) and SPI. The RTC_B module is enabled only when LFXT is used - confirmed as available in MSP430FR5x6x devices including MSP430FR5967.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power FRAM microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430FR5969IRGZR | 64 KB FRAM, 2 KB RAM, same package and peripheral set - higher memory capacity with identical pinout and software compatibility. | Suitable for applications requiring larger firmware image or extended data buffering (e.g., multi-sensor fusion). | Select when future-proofing memory headroom is needed without changing PCB layout. |
| MSP430FR5947IRHA | 32 KB FRAM, 1 KB RAM, but in 40-pin VQFN (RHA) with LFXT-only clock - no HFXT support and 8 fewer GPIOs. | Targeted at cost-sensitive, lower-I/O designs where high-frequency crystal is unnecessary (e.g., basic RTC + ADC nodes). | Choose for simplified BOM and reduced board area when HFXT and extra I/O are unused. |
Compared with MSP430FR5969IRGZR, the MSP430FR5967IRGZR trades FRAM/RAM capacity for identical low-power performance and peripheral feature set; versus MSP430FR5947IRHA, it adds HFXT support and 8 additional I/Os - enabling higher-speed communication and more complex sensor interfaces.

FAQ
What is the maximum operating frequency of the MSP430FR5967IRGZR?
The MSP430FR5967IRGZR supports a maximum system clock frequency of 16 MHz using its factory-trimmed DCO oscillator. This frequency is achievable across the full 1.8 V–3.6 V supply range and enables real-time signal processing in sensor applications while maintaining ultra-low-power operation in active mode (≈100 µA/MHz).
Does the MSP430FR5967IRGZR support hardware-accelerated cryptography?
Yes, the MSP430FR5967IRGZR includes a dedicated AES256 security coprocessor that performs encryption and decryption operations independently of the CPU. This allows secure firmware updates and protected data storage without impacting real-time application performance - a key capability confirmed in the device's feature list and functional block diagram.
Can the MSP430FR5967IRGZR operate with only a 32-kHz crystal, or is a high-frequency crystal required?
The MSP430FR5967IRGZR supports both LFXT (32 kHz crystal on PJ.4/PJ.5) and HFXT (high-frequency crystal on PJ.6/PJ.7) - neither is mandatory. LFXT is required for RTC calendar operation and LPM3.5 mode; HFXT enables higher-speed system clocks beyond DCO limits. The device functions fully with LFXT only, as verified in the device comparison table and functional block diagram.
How many analog input channels does the ADC12_B module support on the MSP430FR5967IRGZR?
The ADC12_B module on the MSP430FR5967IRGZR supports up to 16 external analog input channels (A0–A15) plus 2 internal channels (temperature sensor and reference voltage). This is explicitly stated in Table 3-1 (Device Comparison) and confirmed in Section 1.1 Features - enabling simultaneous monitoring of multiple sensors without external multiplexing.
Is the MSP430FR5967IRGZR pin-compatible with other devices in the MSP430FR596x family?
Yes, the MSP430FR5967IRGZR shares the same 48-pin VQFN (RGZ) package and pinout with MSP430FR5968IRGZR and MSP430FR5969IRGZR - confirmed by identical pin diagrams and signal descriptions in the datasheet. This allows drop-in replacement within the RGZ-based MSP430FR596x series for memory-scaling design iterations.
